This is why I learned LONG ago to wind my OWN, when there's some
current/voltage combo that is not readily-available "from the catalogs"! You might
consider paralleling TWO 10-amp transformers, or three 6.5 amp secondaries. Are
you sure you have done the math right to START with? DC-supplies for
chopper-drives (Gecko, etc.) should be figured on WATTAGE, not current (as was sadly
necessary, however, for unipolar "L/R drives"!)

Less likely is to find two 20-amp/18-volt secondary transformers. In series,
that would work, too, if you REALLY need 20 amps! Whew, that's a lot!
